This is our starting slide.

Intro

  • Goal
  • Data (F45–F170)
  • Two species (LT vs SMB)

Why fish hydroacoustics?

  • Non-invasive monitoring
  • Management: distinguish LT vs SMB
  • Question: can the FRC (45–170 kHz) classify species?
  • Outcome: scalable pipeline for species ID & trends

About the dataset

  • ~30k rows × 302 variables; two species (LT, SMB)
  • Processed in Echoview
  • Signals: F45–F170 (Frequency Response Curve)
  • Context: morphometrics, depth, speed, orientation
  • Focus today: frequency data only for classification

Acoustic fingerprints: the Frequency Response Curve (FRC)

  • Different echoes (45–170 kHz) → the FRC
  • Species show distinct curve shapes
  • Hypothesis: FRC alone can separate LT vs SMB
